The next talk of the Virtual Babelsberg Starry Nights of the Leibniz Institute for Astrophysics Potsdam (AIP) on the topic "Binary stars in exchange" (German) by Daniel Pauli from the University of Potsdam will be broadcast on the YouTube channel “Urknall, Weltall und das Leben” (Big Bang, Universe and Life) from Thursday, 21 March 2024.

This time, Daniel Pauli from the University of Potsdam will be a guest at the Virtual Babelsberg Starry Nights with his latest research findings. His lecture entitled "Binary stars in exchange" will be broadcast online on Thursday from 8 pm. Daniel Pauli will talk about massive stars that have many times the mass of our sun. They are very hot and bright and therefore easy to observe. Most massive stars are born as binary stars so they can interact with each other during their lifetime. If the stars exchange mass, this has drastic effects on their future development. But what exactly do we know about these short-lived interactions in binary star systems?

Usually on the 3rd Thursday of each month, starting at 8 p.m., the lectures of the Babelsberg Starry Nights become available at

and via the YouTube channels "Urknall, Weltall und das Leben" (Big Bang, Universe and Life) and "videowissen" and can be viewed afterwards at any time.

The key areas of research at the Leibniz Institute for Astrophysics Potsdam (AIP) are cosmic magnetic fields and extragalactic astrophysics. A considerable part of the institute's efforts aims at the development of research technology in the fields of spectroscopy, robotic telescopes, and E-science. The AIP is the successor of the Berlin Observatory founded in 1700 and of the Astrophysical Observatory of Potsdam founded in 1874. The latter was the world's first observatory to emphasize explicitly the research area of astrophysics. The AIP has been a member of the Leibniz Association since 1992.
